Surface bioconjugation of antimicrobial peptides (AMP) onto nanoparticles (AMP-NP) is a complex, multistep, and time-consuming task. Herein, microfluidic system for the one-pot production AMP-NP was developed. Norbornene-modified chitosan used NP (NorChit-NP), thiolated-AMP grafted on their surface via thiol–norbornene "photoclick" chemistry over exposure two parallel UV LEDs. The MSI-78A AMP selected due to its high activity against priority (level 2) antibiotic-resistant gastric pathogen:...
Covalent conjugation of antimicrobial peptides (AMP) is considered an effective approach to overcome their potential degradation in vivo. As the high cost AMP-based therapies one major hurdles toward clinical application, it urgently needed explore yield reactions. Herein, highly efficient thiol–norbornene photoclick chemistry (TNPC) was explored for AMP grafting onto chitosan. Norbornenes were introduced chitosan (NorChit) aqueous/organic system, followed by UV-triggered N- and C-terminus...
Impaired angiogenesis in skin chronic wounds prolongs inflammation and compromises wound healing. Several strategies have been attempted to improve vascularization, such as application of growth factors, like the vascular endothelial factor (VEGF). However, VEGF is expensive, has a short half-life vivo associated tumorigenesis when used high concentrations. QK peptide shorter (15 amino acids), synthetic, VEGF-mimetic with improved stability lower production cost. residence time may be...
A novel blue-emitting fluorescent alginate derivative has been successfully synthesized in a simple two-reaction step protocol. The developed material showed to be biocompatible and traceable upon long periods of incubation physiologic conditions.
It is key to fight bacterial adhesion prevent biofilm establishment on biomaterials. Surface immobilization of antimicrobial peptides (AMP) a promising strategy avoid colonization. This work aimed investigate whether the direct surface Dhvar5, an AMP with head-to-tail amphipathicity, would improve activity chitosan ultrathin coatings. The peptide was grafted by copper-catalyzed azide-alkyne cycloaddition (CuAAC) chemistry either its C- or N- terminus assess influence orientation properties...
